- Specification of Letters Patent k Patented' IG, 1906 To all zohom'it mbty concern.-

' Be it known that we, ADoLrHLANG and HARPER F.v SMITH, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and usef'ul Lamp, of which. j'the following is a specification; I Ourtinvention' consists of a novel construe tion of a lighting devicein which both the air and the gas are separately heated before entering the chamber in which they -unite.

The oxygen in the heated air'unites with the heated as to form a gas and thecOmbination an cohesionbetween these two heatedgases form-a distinct and separate gas, which produces an intense heat, and when this heat comes in contact with an incandescent body,"v such as the mantle of a lamp, averystrong and brilliantlight is produced. The volume.

of air traversing the heated air-chamber will preferably begreater in proportion than the volume of gas passing through the heated gas-chamber, and as the heated air ,leaves and simplified construction of heating-fcham I bers in which one or more tubesare employed, 1 said tubes b ing connected and arranged in any suitable manner, either vertically, horiareconducted. p v It further consists of a novel construction zontally,'spirally, orotherwise, it being only essential that the air and the.gas'b p 'rately heated. y I

The gas passing through the outlet 13 and into the space 2,6,.surrounding the air-outlet 25, is drawn or forced by the air passing through said outlet into the chamber 27. The combination between the heated gas and the heated air forms a distinct gas, which is a gas having a high percentage of oxygen, since the oxygen in the heated air combines with the heated gas and-oxidizes the same. This gas passes through the chamber 27 into the chamber-28, which forms a continuation of the chamber 27 in the casing 29, which is suitably secured to the chamber 27. casing 29 is provided in the present instance with two :burner-tips 30 although it is evident that the number of burner-tips employed may be varied according to requirements. v

31 designates a lug extending outwardly from the-casing 29 and having secured therein, .by means of set-screws32, mantle-su,p porting rods 33, which are bent at the outer end. inthe form-ofi-a hook 34, on which the mantle35 is supported. 36 :designatesa lug or projection extending from the casing 1'29, on which is adjustabl-y mounted, by means of set-screws or equivalent devices 37, abracket' 38, adapted to support the globe 39. g

in the embodiment shown in Fig. 2 we have shown the airiand gas tubes as extending horizontally instead of vertically, it 'being apparent that -these itubes may be arranged either horizontally, perpendicularly,

'or otherwise, with respect to the heating-device and that 'the operation will be the same as in the construction shown in Fig. '1. We have, however, shown means for producing an air-pressure, and in this embodiment 45 designates aigas-inl'et pipe having a suitable oontrolling-valve 46, "said pipe 415 being connected with a block 47, provided with a chamber 4:8, having communication with said pipe 45 and also with a pipe-49, one-end of which lis secured in the block 47, the other end thereof being secured-to a block 50, having a chamber'cr passage 51 therein.

the other end thereof being secured to the block 47 and having communication with the chamber 72, which leads to the-air-outlet 73 the latter being in advance of the gas-outlet 58 in order that the heated gas coming from the gasoutlet 58 into the chamber 74,-surroundingthe -air+outlet 73, will bedrawn into the chamber- 75 by means of the heated air coming through the nozzle 7 3.

. 81 designates the globe, which issuitab'ly secured'inra bracket 82, supported 0111a lug or extension 83, extending from the :casing 76. A flang'e84, fixed to the reflector 83, prevents the heat from-escaping 'between the re-' flector and therglobe. The operation of the lam will be readily apparent. Both the aair-in st :and the aslip ber 26 a highly-heated condition and will bedrawn into the chamber 27. The air comcap 4 and the block 7 through the discharge-' nozzle :into the chamber 27. As both the air and the gas have been se arately heated of the air, which enters t .to ahighdegree, the, gas 'wil be oxidized in the chambers 27 and 28 and a gas produced- Which is a gas having a high percentage of oxygen This 'gas produces an intense heat, and this heat coming incontact with the incandescent mantle produces a've'ry intense and very brilliant light, i

being connected with the atmosphere, in the embodiment shown in Fig. 2 we have shown a bellows actuated by a water-motenfor producing the'desired pres we 'or compression file inlet-pipe 62 and passes through the pipes 64, 67, 79, and 71 and the chambers 63, 66, 68, 70, 'and- 7,

' registering therewith, and through the -noz zle 73 into the chamber 75. The gas entering in the ipe will pass through the chamber 48 an pipes 49, 52', 54, and 56 and chambers 51, 53, 55,'and 57 to the'gas-ou'tlet 58,

thence into the chamber 74, surrounding the air-inlet 73, into the chambers 75 -and 77, where the same action takes place as in the construction shown in Fig. 1 and the gas produced passes to the burner-tip 78 and the incandescent mantleSO in the same manner.

4 It will be readily apparent that the pro ortion of heated air and heated gas Whic is t the air may be varied as desired, and that this may be done by any suitable means such as a blower, fan, or other deviceand still be within the scope of our invention.

' more intense and bril iant light than the It will also be apparent that while we'have shown the separate heating-tubes as, being parallel to each other and arranged either erpendicularly or horizontaliy the same may hearranged at any desired angle to each other or to the source-of heat or sp1rally arranged, according to requirements.

A lamp of this character may be so constructed as to vaporize any volatile oil and this heated va'por carried through the tubes to the gas-outlet, where it will unite with the heated airentering the chamber in which the union takes place and form the gas in recisely the same manner as already descrl ed in the as process.

We ave found in practice that in a lighting device constructed in the novel manner herein described not'onl is produced a much prior devices now in use, but also the consumption of gas in proportion to the amount of produced 1s greatly decreased. By

separately superheating the gas and the air and then bringing these two gases together in the right proportion while in a highly heated condition the gases oxidize, and the gas thus produced not only provides a more intense light and is more. economical with the use o'f the gas, but the life of the incandescent mantle willbe prolonged.

We are aware that 1t has heretofore been proposed to partially heat the gas and then I that it has also been proposed to mix the air ,-Whi-le in Fig. '1 we have shown the air as.

and gas in its normal stateand then heat it;

but in so far as we are aware we are the first in the art to separately heat the air and separately heat 'the gas and then bring the two products into a se arate chamber, in which they may unite to 'orm a gas which is a fixed product and which on cooling has substantially the same quality and efliciency as when in a heated condition,' and our claims to these features are to be interpreted with corresponding scope.

It willbe apparent that'the heat given off air-pipes andgas-pipes, so that the heat from the burners is employed .to automatically superheat both the air and the gas, and the heatedair and gas thus reduced unite to form the gas which feeds t e burners.

It will be apparent that themotor 59 may be any of the usual or conventional typesof ye for creating moderate pressures at fesired water or similar motors which are em points, and as the same forms per se..no

part of our present invention .we have deemed in unnecessary to describe the same in detail.

It will be evident that various ehan es ma be made bythose skilled in the art which wil come withi-n the scope of our invention, and wetdo not, therefore, desire to be limited in everyinstance to the exact construction herein shown and described.

by the lighting device has free access to the Having thus described our invention, -what we claim as new, and desire to secure by Letters Patent, is v 1.
